Which technique collects expert opinions asynchronously via written responses to forecast future events?

• A. Delphi Technique
• B. Brainstorming
• C. Surveys
• D. Interviews

Answer: (A)

This question tests understanding of gathering expert judgments over time through an iterative, written process. The Delphi Technique uses a structured, multi-round approach where experts respond to questionnaires in writing, often anonymously. After each round, responses are summarized and shared, and experts can revise their views in subsequent rounds. This asynchronous, written feedback helps build a consensus about future events while reducing the influence of dominant personalities and groupthink.

Brainstorming tends to be a quick, in-person idea generation activity and is not focused on forecasting through written rounds. Surveys collect opinions in a single pass without the iterative refinement that characterizes Delphi. Interviews involve direct, usually real-time conversations and are not designed for asynchronous, multi-round written responses aimed at forecasting.
